Overview
- Screening for thrombophilia depends on the clinical presentation.
- Screening should be avoided in the setting of major transient risk factors.
Screening
- The American Society of Hematology recommends against thrombophilia screening in adult patients with venous thrombosis in the setting of major transient risk factors which include surgery, trauma, or prolonged immobility.[1]
- However, given the associated risks for recurrent thrombosis, patients who have significant risk factors including a positive family history or concurrent treatment with hormonal therapies should seek expert consultation.
- Therefore, screening may be useful in the following situations.[2]
- Asymptomatic screening: First degree relatives of patients with homozygosity for factor V leiden, antithrombin deficiency, protein C or S deficiency and anticipated hormone therapy or pregnancy.
- Syptomatic screening (patients with acute thrombus) may be useful in patients with certain clinical presentations.
- Screening can be expensive, and are often performed at inappropriate times.
- Refer to thrombophilia laboratory findings for more information on specific screening tests.
